この考案は内燃機関などに装着されるエアクリ

が、実開昭56−45154号公報に開示されている。(Prior Art) Conventional air cleaners are designed to remove moisture from the air for purposes such as supplying combustion air for internal combustion engines. This can be achieved by impregnating the filter element's filter material with a water repellent or water absorbing agent, or by forming a swirling flow path around the filter element's outer periphery of the casing body, where water is centrifuged and dropped to the lower part of the casing. Materials collected in a dust pan are used. Further, Japanese Utility Model Application Publication No. 56-45154 discloses a method in which the liquid is centrifuged before flowing into the casing body.

を接続する場合には採用することができない。(Problem to be solved by the invention) Among the water separation means currently in use as described above, the former method is ineffective because it allows the chemical to act only for a very short period of time when it passes through the filter medium. There is also large variation in performance. Furthermore, the latter requires a cylindrical casing body and a dust pan and is large, making it unsuitable for air cleaners that require a flat and compact shape, such as air cleaners for passenger cars. Furthermore, in the device disclosed in Japanese Utility Model Application Publication No. 56-45154, the swirl vane is attached to the upstream side of the inlet pipe, so the structure on the inflow side is long with respect to the casing body, and it is sufficient to shorten the swirl vane. Water separation effect cannot be obtained. Furthermore, it cannot be used when connecting an air intake duct or the like to the upstream side of the inlet pipe.
（課題を解決するための手段）

旋形蛇腹状の案内壁を設け、両者の間〓に吸水剤

口に面した斜面に開口を設けたものである。(Means for solving the problem) This invention provides a spiral bellows-shaped guide wall along the inner wall of the inlet pipe, stores a water-absorbing agent between them, and connects the guide wall to the inlet pipe inlet. An opening is provided on the slope.

れて所要の個所へ運ばれる。(Function) The air taken in from the inlet pipe enters while turning in a spiral shape due to the action of the guide wall. At that time, when the water is centrifuged by centrifugal force and collides with the guide wall, the opening is open toward the inlet pipe inlet, so the water flows from here between the guide wall and the inner wall of the inlet pipe. It penetrates and is absorbed by the water-absorbing agent stored there. The intake air thus becomes dry air and is filtered by the filter element and transported to the required location.

で濾過されアウトレツトパイプ５へ出る。(Example) An example is shown in FIG. The air cleaner 1 has a well-known honeycomb element 2 housed in a casing 3. An inlet pipe 4 and an outlet pipe 5 are attached to the casing 3. A spiral bellows-shaped guide wall 7 with a corrugated cross section is attached to the inner wall of the inlet pipe 4, and a water absorbing agent 8 is accommodated between the guide wall 7 and the inlet pipe 4. Water absorbing agent 8
Suitable examples include vinyl acrylate alcohol copolymer and sodium acrylate polymer. A slit-shaped opening 9 is provided on the slope of the guide wall 7 facing the inlet pipe entrance 4a. FIG. 2 shows details of the guide wall 7 and the slit-shaped opening 9. Intake air enters from the inlet 4a of the inlet pipe 4, is guided by the guide wall 7, and becomes a swirling flow. Moisture is separated by centrifugal force and enters between the guide wall 7 and the inlet pipe 4 through the opening 9 and is absorbed by the water absorbing agent 8. Dehydrated air is transferred to honeycomb element 2
is filtered and exits to outlet pipe 5.
